The side of a square is 3x - 2. Express the
perimeter of the square in terms of x.

The value of x is 2/3.

Step-by-step explanation:

The perimeter of a square is 4s.

Substitute the value and simplify.

4( 3x - 2 )             Distribute

12x - 8                  In this case this is an equation

12x - 8 = 0             Add 8 on both sides

     12x = 8              Isolate the variable by dividing 12 on both sides

        x= 2/3

 You must isolate the variable in order to solve equations with variables.

Isolating variable is basically when you divide, multiply, add, or subtract to put a variable on ONLY one side of the equation.

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
